Need a mic? Look into this ModMic. While I can't vouch directly for or against it, the idea is sound, and it lets you use it with any headphone you want instead of being limited to a few headphone models.

At $145 for the HD 558 + $33 for the ModMic, though, that's not a whole lot of savings compared to a PC360 at $200. On the other hand, you can't move the PC360's mic to a better headphone later on if you want to climb the upgrade ladder. On the other other hand, the PC360's mic is naturally better integrated into the whole thing.

Decisions, decisions...

Thanks for the info, but I have of course I'll buy the PC 360, plus the mic quality is finally want to know if the Sennheiser PC 360 headphones are good for a sound card Asus Xonar DX / XD.
